GAS-BURNING FLAT-IRON HEATER.

Application filed March 27, 1914. Serial No. 827,531.

Toall whom it may concern r 1 'Be it known that 1, Ross M. G. PHILLIPS,

' ing Flat-Iron Heaters; and I do hereby declare the following, whentaken in connection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description'of.the same, and which said drawings constitute part of this application,and represent, 1n-

Figure 1 a plan view of a gas-burning flat-iron heater constructed inaccordance with my invention, showing two burnerunits. Fig. 2 a viewthereof in vertical longitudinal section on the line ab of Fig. 1. Fig.3 a view thereof in transverse section on the line 0(Z of Fig. 1,showing a Valve-operating member in its elevated or gas cut-out positionby full lines, and in its depressed or gas-feeding position by brokenlines.

My invention relates to an improvement in that class of gas-burningflat-iron heaters in which the gas-valves are in part operated by theweight of the irons, the object being to produce at a low cost formanufacture, a simple and convenient device of the character described.

With these ends in view, my invention consists in a gas-burningflat-iron heater having certain details of construction and combinationsof parts as will be hereinafter described and pointed out in the claim.

For the purpose of illustrating my invention, I have shown and describeda heater having two burner-units, but a heater having one burner-unit oran indefinite number of burner-units may be constructed in accordancewith my present invention. As herein shown, I employ two skeletonburner-frames 2 and 3 arranged side by side and supported at their endsupon the front and rear side bars of an oblong heaterframe 4 having legs5 at its corners. As shown the left-hand burner-frame 2 is provided withan integral grid-iron like grill 35, which overhangs the left hand endof the heater-frame 4E and which is furnished for the temporary storageof a reserve iron. Beneath the respective burner-frames 2 and 3 I locatecorresponding burners 6 and 7 Specification of Letters Patent.

having burner-ports 8 arranged along their edges in series. Each burner6 is formed at itsforward end with an assembling-stud 9 adapting it tobe supported in a flange 10 depending from the forward end of theburner-frame under which it is located. Each burner is provided at itsrear end with an upwardly extending suspension-flange 11 terminating ina positioning-finger 12 enter ing a slot 13 in a horizontal flange 14 atthe rear end of its burner-frame. However, the

particular construction of the burner-frame and burners may be varied.The said burners are respectively provided at their rear ends withintegral conical mixing-chambers 15 receiving valves 16 and 17 united byelbows 18 connected by nipples 19 with a T 20 to which gas is broughtthrough a supplypipe 21 containing an ordinary key which is not shown.The valve-plugs (not shown) within the valves 16 and 17 are normallymaintained in closed positions by springs 22 which may be located Withinthe valves if desired, as shown in my co-pending application filedFebruary 21st, 1911, Serial No. 820,151. For the rotation of the saidplugs, the same are provided with crank-like valvestems 23 enteringslots 24 in the rear ends of long valve-actuating levers 25 which rockupon screw-studs 26 entered into threaded counter-bores in the ends ofalined hubs 27 cast integral with the burners and located between thesame and the mixing-chambers 15 thereof. The forward ends of therespective levers 25, pass under the lateral arms 28 (Fig. 1) ofcradle-like valve-operating members each formed from a single piece ofheavy wire and each comprising two upstanding, inclined fiat-iron arms29, united at their rear ends by a bow or loop 30, the forward ends ofthe said arms being bent inward toward each other to form pintles 31, bywhich the said members are pivotally mounted in the forward ends of theburner-frames 2 and 3. The said members are normally maintained inelevated positions above the plane of the burnerframes by means of thesprings 22 aforesaid, and as indicated by full lines in Figs. 2 and 3.The valves 16 and 17 are provided with pilot-light couplings 33 fromwhich small pilot-light pipes 34 lead forward alongside of the burnerports 8 of the respective burners 6 and 7 Normally gas is excluded fromthe burners 11 0 6 and 7 by means of the normally closed valves 16 and17, while the pilot-lights remain lighted. When a fiat-iron is placedover either burner, the valve-operating member thereof will be depressedto the level of its plane and act through its appropriatevalve-actuating lever to open the appropriate valve. The valveoperatingmembers may be operated by flat-irons placed over the burners lengthwisetherewith, or cross-wise thereof. The said burner-frames are adapted inlength to accommodate two irons placed side by side over it crosswise,and the arms 29 of the valve-operating members are long enough to beengaged and held down by either iron if either one is removed. Myimproved heater may therefore be used when it is provided with twoburner units for concurrently heating from one to four irons. Theaddition of more burner units would correspondingly increase itscapacity. As shown the levers are projected in front of the heater-frame4 to enable them to be manually operated by the ironer for shutting oilthe gas and so extinguishing the flame before she removes a heated iron.1

I claim In a gas-burning fiat-iron heater, the coming parts normallyextending above the same, a pair of normally closed valves connectedwith the respective burners at the rear ends thereof, and a pair ofvalve-actuating levers located below the said grill between the saidburners and connecting the respective valve-operating members and valvesfor the opening of the latter upon the depression of the said members bythe appropriate placing of fiat-irons upon the a grill, the forward endsof the said levers be ing extended into position for their independentmanual operation.

In testimony whereof, I have signed this it specification in thepresence of two subscribing witnesses.
